The ejection member includes a receiver and an ejection portion. The receptacle can be squeezed by an operating member (eg, a pin). The eject member pivots from the received position to the eject position when the receptacle is squeezed. When the eject member pivots toward the eject position, the eject portion ejects the object. When the receiver receives excessive force from the operation member, the support portion comes into abutment with the receiver to support the receiver.

Description

Connector

technical field

The invention relates to a connector capable of being connected to a card such as a Subscriber Identity Module (SIM) card.

Background technique

For example, this type of connector is disclosed in JP-A 2008-108695 or US2009/267677A, the contents of which are hereby incorporated by reference.

The connector of JP-A2008-108695 can be connected to a memory card such as a multimedia memory card (MMC). The connector is configured to receive and eject a memory card (the card) mounted on the tray. In other words, the object that is received directly in and ejected from the connector is the bracket. The bracket is formed with a hole into which a pin (operating member) can be inserted. When the pin inserted through said hole squeezes the push lever, the locked state is unlocked by means of the locking mechanism, so that the card is ejected together with the tray. The aforementioned ejection mechanism is provided in the connector itself.

Similarly, the connector of US2009/267677A is capable of connecting to a card such as a SIM card mounted on a cradle. Similar to the connector of JP-A2008-108695, the object that is directly accommodated in and ejected from the connector is a bracket. However, an ejection mechanism configured as an ejection tray is provided not in the connector but in an electronic device in which the connector is installed.

The ejection mechanism of JP-A 2008-108695 has a problem in that it is difficult to reduce the size of the connector. Although the ejection mechanism of US2009/267677A can be constructed from a relatively small number of components, the ejection mechanism is provided in the electronic device itself. Therefore, various problems may arise in production (for example, at the time of position adjustment).

Also, the eject mechanism may receive excessive pressing force from the pin (operating member). Therefore, the connector is required to have strength to withstand such excessive crushing force.

Contents of the invention

Therefore, an object of the present invention is to provide a connector having relatively high strength against pressure from an operating member while including an ejection mechanism having a structure that can be easily simplified and simple.

One aspect of the present invention provides a connector capable of receiving at least a part of an object. The connector includes an eject member and a support portion. The eject member is pivotable between an eject position and a received position. The ejection member includes a receiver and an ejection portion. The receptacle has a front surface and a rear surface. The front surface of the receiver is configured to be pressed in a pressing direction by using an operating member different from the connector. The eject member is designed to pivot from a receiving position to an eject position when pressing the front surface in a pressing direction. When the eject member pivots toward the eject position, the eject portion ejects the object in an eject direction opposite to the pressing direction. The supporting portion is located within a predetermined range in a vertical direction perpendicular to the ejecting direction. The upper and lower ends of the receiver in the vertical direction define upper and lower limits of the predetermined range, respectively. The support portion comes into abutment with the rear surface of the receptacle when the front surface of the receptacle receives so much force as to force the ejection member to pivot out of the ejected position. Said abutment of the support portion backs up the receiver.

An appreciation of the objects of the invention and a more complete understanding of its structure may be had by studying the ensuing description of the preferred embodiment and by referring to the accompanying drawings.

The insertion hole 140 is configured to guide the inserted operation member. The bracket 100 is also provided with a force receiving portion 120 . The force receiving portion 120 receives a force in the positive X direction (ejection direction) when the tray 100 is operated to be ejected.

3, in addition to the aforementioned ejection member 50, the connector 10 according to the present embodiment also includes a plurality of contacts 20 each made of a conductive material, a holding member 22 made of an insulating material, and a holding member 22 made of a metal. The cover shell 30. The contacts 20 are connectable to respective connection terminals of the card (not shown) accommodated in the housing portion 12 . The holding member 22 holds the contact 20 . The cover case 30 forms the accommodation portion 12 together with the holding member 22 . The eject member 50 is connected to the cover case 30 .

Referring to FIGS. 1-5 , the cover case 30 has an upper portion 30U on its upper side (ie, positive Z side). The eject member 50 is connected to the upper portion 30U of the cover case 30 so as to be pivotable. As shown in FIGS. 1 and 2 , the cover case 30 has a front end 30F and a rear wall 30B respectively located on opposite ends in the X direction. The cover case 30 is formed with a supporting structure for supporting the ejection member 50 . The aforementioned support structure is provided on the upper portion 30U so as to be positioned closer to the front end 30F than the rear wall 30B. The support structure mainly includes a shell-side stopper 32 , a pivot member 34 , a first holding portion 36 , a second holding portion 37 and a third holding portion 38 . The case-side stopper 32 is located on the positive Y side of the upper portion 30U in the Y direction (transverse direction), and is located near the front end 30F in the X direction. In detail, the upper portion 30U is partially cut away to form an opening portion extending in a direction oblique to the X direction. The opening portion has a front edge (ie, positive X-side edge). The front edge of the opening portion is bent to protrude in the positive Z direction (ie, protrude upward) so as to form the case-side stopper 32 . The case-side stopper 32 faces obliquely rearward (ie, faces in a direction oblique to both the negative X direction and the negative Y direction). The pivot member 34 is disposed obliquely behind the case-side stopper 32 . In detail, the case-side stopper 32 and the pivot member 34 are located on a line oblique to both the negative X direction and the positive Y direction. The pivot member 34 is a small part parallel to the YZ plane. In detail, the pivot member 34 is extended in the Y direction while protruding in the positive Z direction (ie, upward). The first holding portion 36 and the second holding portion 37 are provided to place the pivot member 34 therebetween in the X direction (front-rear direction). The upper portion 30U is formed with two grooves. One of the two grooves is formed between the first retaining portion 36 and the pivot member 34 . The remaining one of the grooves is formed between the second holding portion 37 and the pivot member 34 . Each of the first holding portion 36 and the second holding portion 37 protrudes in the positive Z direction to form a space on the negative Z side (ie, lower side) thereof. Spaces below the first holding portion 36 and the second holding portion 37 communicate with the grooves, respectively. The third holding portion 38 is formed at a position opposite to the pivot member 34 that straddles the case-side stopper 32 in the Y direction (ie, formed on the negative Y side of the upper portion 30U). The upper portion 30U also has a groove formed between the third retaining portion 38 and the pivot member 34 . The third holding portion 38 protrudes in the positive Z direction to form a space on the negative Z side thereof (ie, under the third holding portion 38 ). The space below the third holding portion 38 communicates with the groove beside the third holding portion 38 .

Referring to FIGS. 6-8 , the ejection member 50 is formed by bending a single sheet metal to have a plate-like body 52 . As can be seen from FIGS. 1-5 , the body portion 52 extends parallel to the XY plane in a state in which the eject member 50 is connected to the cover case 30 . As shown in FIGS. 6 and 7 , the body portion 52 is formed with a pivot portion 54 . The pivot portion 54 is a through hole having a dumbbell shape or a figure-eight shape. The pivot portion 54 is located near a third position of the body portion 52 in the longitudinal direction (ie, the direction in which the body portion 52 is extended). As can be seen from FIGS. 1 , 2 and 4 , the pivot portion 54 receives the pivot member 34 of the cover shell 30 . When the pivot piece 34 is received in the pivot portion 54 , the eject member 50 is supported by the cover case 30 to be pivotable. The eject member 50 is pivotable between a storage position (see FIG. 1 ) and an eject position (see FIG. 2 ). As shown in FIGS. 6 and 7 , according to the present embodiment, the body 52 is provided with a pivot stop 56 at its front edge. In detail, the pivot stopper 56 is located near the halfway position of the body 52 in the longitudinal direction. As shown in FIG. 2 , the pivot stop 56 abuts the case-side stop 32 of the cover case 30 when the eject member 50 is in the eject position. Therefore, the eject member 50 cannot be pivoted out of the eject position. In other words, the eject position is one of the boundaries of the pivot range of the eject member 50 .

As shown in FIGS. 6 and 7 , the eject member 50 is provided with an eject portion 60 and a receiving portion 70 . The ejection portion 60 and the receiving portion 70 are respectively disposed on opposite sides across the pivot portion 54 (ie, across the pivot center of the ejection member 50 ). In other words, the pivot portion 54 is located between the eject portion 60 and the receiving portion 70 .

The receiving portion 70 is configured to receive the front end of the operating member (pin) when the accommodated tray 100 is ejected. As shown in FIGS. 5-7 , the receiving portion 70 according to the present embodiment includes a receiver 72 and four side walls 74 . The receiver 72 has a rectangular shape to have four sides. The side walls 74 are provided to respectively correspond to the four sides of the receiver 72 . As shown in FIG. 4 , the receiving portion 70 is designed such that when the eject member 50 is located at the accommodation position, the rod-shaped portion 130 (in particular, the insertion hole 140 ) of the bracket 100 and the receiving portion 70 are located in the direction extending in the X direction (front-rear direction). single line. Therefore, when the operation member (pin) is inserted and pushed into the insertion hole 140 in the negative X direction, the front end of the operation member (pin) is smoothly received in the receiving portion 70 . Therefore, the insertion hole 140 formed in the bar portion 130 functions as a guide portion that guides the operation member (pin) toward the receiving portion 70 .

The receiver 72 according to the present embodiment is the farthest wall of the receiving portion 70 in the negative X direction (pressing direction) when the eject member 50 is located at the accommodated position (see FIG. 1 ). The receiving portion 70 has a box shape opened in the positive X direction (ejection direction). The receptacle 72 is directly connected to the outermost side wall 74 in the positive Y direction, while not being directly connected to the other side wall 74 .

Receptacle 72 has a front surface 72F and a rear surface 72B. The front surface 72F of the receiver 72 is arranged to be pressed in the negative X direction by using an operation member different from that of the connector 10 . More specifically, when the eject member 50 is located at the accommodated position (see FIG. 1 ), it is possible to insert the front end of the operation member into the receiving portion 70 to press the front surface 72F of the receiver 72 . When the front surface 72F is pressed in the negative X direction, the eject member 50 is designed to pivot on the pivot portion 54 from the accommodated position to the eject position (that is, until the pivot stop 56 and the case side stop 32 form contact). When the eject member 50 pivots toward the eject position, the eject portion 60 ejects the tray 100 in the positive X direction. In detail, when the eject member 50 pivots, the eject portion 60 moves in the positive X direction (pressing direction) to apply force to the force receiving portion 120 of the bracket 100 in the positive X direction. The aforementioned force pushes out the force receiving portion 120 along the positive X direction. Accordingly, the tray 100 accommodated in the accommodation portion 12 is ejected in the positive X direction (ejection direction). As can be seen from the above description, the eject mechanism according to the present embodiment has a simple structure. Also, it is easy to simplify the eject mechanism.

As shown in FIGS. 1 and 2, the eject member 50 is provided with a first held portion 76, a second held portion corresponding to the first holding portion 36, the second holding portion 37, and the third holding portion 38 of the cover case 30, respectively. 77 and the third held part 78. As shown in FIGS. 6 and 7 , the first held portion 76 and the second held portion 77 are positioned to face each other across the pivot portion 54 . More specifically, the first held portion 76 and the second held portion 77 are arranged such that a line connecting the first held portion 76 and the second held portion 77 crosses another line connecting the ejection portion 60 and the receiving portion 70 . The third held portion 78 is provided at a position farthest from the pivot portion 54 . More specifically, the third held portion 78 according to the present embodiment is formed on the end portion of the eject member 50 in the longitudinal direction. Each of the first held portion 76 , the second held portion 77 and the third held portion 78 is inclined downward from the body portion 52 in the negative Z direction (ie, downward). In other words, each of the first held portion 76 , the second held portion 77 and the third held portion 78 is located below the body portion 52 . As can be seen from FIGS. 1 and 2, the first held portion 76, the second held portion 77, and the third held portion 78 are received in the first holding portion 36, the second holding portion 37, and the third holding portion, respectively. 38 in the space below. As can be seen from FIGS. 1 and 2 , the first held portion 76 , the second held portion 77 and the third held portion 78 can be below the first held portion 36 , the second held portion 37 and the third held portion 38 Move in the XY plane in the space. Movements of the first held portion 76 , the second held portion 77 and the third held portion 78 in the positive Z direction are regulated by the first holding portion 36 , the second holding portion 37 and the third holding portion 38 , respectively. In other words, the eject member 50 is held by the upper portion 30U of the cover case 30 so as not to come off from the cover case 30 while being able to pivot between the accommodated position and the ejected position.

As shown in FIGS. 1 , 2 and 4-8 , the eject member 50 according to the present embodiment is provided with a support portion 80 . The support portion 80 according to the present embodiment is integrally formed with the eject member 50 . In other words, the support portion 80 according to the present embodiment is a part of the ejection member 50 . The support portion 80 comes into abutment with the rear surface 72B of the receiver 72 when the front surface 72F of the receiver 72 receives a force so excessive as to force the eject member 50 to pivot out of the eject position. This abutment of the bearing portion 80 supports (ie, supports) the receiver 72 so as to prevent the receiver 72 from being deformed and damaged. The support portion 80 according to the present embodiment is almost in contact with the rear surface 72B of the receiver 72 when no load is applied to the receiver 72 . However, the support portion 80 may be configured differently as long as the receiver 72 is prevented from being permanently deformed in the negative X direction. For example, the support portion 80 may be provided to be separated from the receiver 72 in a natural state (ie, a state where no force is applied to the receiver 72 ). However, if the distance between the support portion 80 and the receiver 72 is too large, the receiver 72 may not be properly supported when the receiver 72 receives excessive force. Therefore, it is preferable that the distance between the support portion 80 and the receiver 72 in a natural state is smaller than or equal to the plate thickness of the metal plate forming the ejection member 50 . The support portion 80 according to the present embodiment is configured as above so that relatively high strength can be obtained.

As shown in FIG. 8 , the support portion 80 is located just behind the receiver 72 . In detail, the receiver 72 has an upper end 72U and a lower end 72L in the Z direction (vertical direction). The upper end 72U and the lower end 72L of the receiver 72 define upper and lower limits of the predetermined range R, respectively. The support portion 80 is located within a predetermined range R in the Z direction (vertical direction). The support portion 80 receives a force in the negative X direction in a supported state where the support portion 80 supports the receiver 72 . The pivot stopper 56 receives a force in the negative X direction from the case-side stopper 32 in the supported state (see FIG. 2 ). It is necessary to prevent the aforementioned two forces (ie, torsional forces in a supported state) from twisting the ejection member 50 . Specifically, it is preferable that the position where the pivot stopper 56 comes into abutment with the case-side stopper 32 is close to the position where the support portion 80 comes into abutment with the receiver 72 in the Z direction. According to the present embodiment, the pivot stopper 56 is located within the predetermined range R. As shown in FIG. Therefore, the pivot stopper 56 comes into abutment with the case-side stopper 32 of the cover case 30 within a predetermined range R (ie, near the abutment position when the support portion 80 comes into abutment with the receiver 72 ). Also, according to the present embodiment, when the predetermined range R is divided into imaginary three equal ranges (specifically, the upper range U, the middle range M, and the lower range L) in the vertical direction, the support portion 80 and the pivot stopper 56 It is located in the middle range M (ie, the middle range of the aforementioned three ranges). Therefore, it is possible to more surely reduce the influence of the torsional force in the supported state. In addition to the torsional force in the supported state, the pop-up member 50 receives another torsional force. In detail, when the tray 100 is ejected, the receiver 72 receives a force in the negative X direction. At the same time, the pop-up part 60 receives a force in the negative X direction from the force receiving part 120 of the bracket 100 (see FIG. 4 ). It is also necessary to prevent the aforementioned two forces (ie, torsional force at the time of ejection) from twisting the ejection member 50 . Therefore, it is preferable to apply force to the force receiving portion 120 within the predetermined range R. As shown in FIG. According to the present embodiment, the pop-up portion 60 is located in the middle range M (ie, the middle range of the aforementioned three ranges) in the vertical direction. Therefore, it is possible to more surely reduce the influence of torsional force when ejecting the tray 100 .

As shown in FIGS. 1 and 2 , the support portion 80 according to the present embodiment is formed by extending the body portion 52 . The support portion 80 is located in the XY plane in a state where the eject member 50 is connected to the cover case 30 . In other words, the support portion 80 has a plate-like shape extending in the XY plane. The support portion 80 may be formed by folding the extended portion of the body portion 52 several times. However, if a single metal plate has sufficient strength for support, it is preferable that the support portion 80 has a single plate-like shape similar to the present embodiment in order to reduce production costs.

As shown in FIGS. 6 and 7 , the support portion 80 according to the present embodiment has a triangular shape. In detail, the support portion 80 is tapered as extending away from the pivot portion 54 (ie, pivot center) of the ejection member 50 . The support portion 80 receives the rear surface 72B of the receiver 72 at its front edge (ie, front end upper edge portion) when excessive force is applied to the receiver 72 . The support portion 80 has the aforementioned tapered shape so that the stress applied to the boundary portion between the support portion 80 and the body portion 52 can be reduced.

The present invention is not limited to the aforementioned embodiments. For example, although the support part 80 according to the foregoing embodiments is formed as a part of the ejection member 50, the support part 80 and the ejection member 50 may be formed independently of each other.

Referring to FIGS. 9-12 , a modified connector 10A according to the foregoing embodiment includes a cover case 30A, an ejection member 50A, and a support portion 80A. The cover case 30A, the ejection member 50A, and the support portion 80A are configured similarly to the foregoing embodiments, except that the support portion 80A is not integrally formed with the ejection member 50A but with the cover case 30A. The support portion 80A is a plate-like portion of the cover case 30A. The plate portion protrudes from the cover case 30A in the positive Y direction so as to be flush with the cover case 30A. The support portion 80A is gradually tapered as it extends in the positive Y direction. The support portion 80A is formed with a front edge obliquely intersecting both the X direction and the Y direction. The position and shape of the support portion 80A are designed to be able to support the receiver 72 . More specifically, as shown in FIG. 12 , when the eject member 50A is located at the eject position (that is, when the pivot stopper 56 and the case-side stopper 32 abut each other), the support portion 80A approaches or contacts the receiver 72 The rear surface 72B. Therefore, when an excessive force in the negative X direction is applied to the receiver 72 , the support portion 80A comes into abutment with the rear surface 72B to support the receiver 72 .

As shown in FIGS. 9-12 , the support portion 80A may be formed on another member than the ejection member 50A (for example, on the cover case 30A). However, the receptacle 72 and support 80 may be more easily positioned if the support 80 is formed as part of the ejection member 50 similarly to the previous embodiment shown in FIGS. 1-8. It is therefore preferable that the support portion 80 and the ejection member 50 are integrally formed similarly to the foregoing embodiments.

This application is based on Japanese Patent Application JP2011-217858 submitted to the Japan Patent Office on September 30, 2011, the contents of which are hereby incorporated by reference.

While there has been described what is believed to be the preferred embodiment of the invention, those skilled in the art will recognize that other and further modifications may be made thereto without departing from the spirit of the invention, and it is intended that All such embodiments that fall within the true scope of the invention are claimed.
